HENRY GUTH, OF NEW YORK, N. Y.

VENTILATING APPARATUS FOR BEER.

SPECIFICATION forming part of Letters Patent No. 242,924, dated June 14,1881.

Application filed April 24, 1880. (No model.)

To all whom it may concern Be it known that I, HENRY Guru, of New York,in the county of New York and State of New York, have invented a new andvaluable Improvement in Ventilating Apparatus for Beer; and I do herebydeclare that the following is a full, clear, and exact description oftheconstruction and operation of the .same, reference being had to theannexed drawduce uniform fermentation in a series of casks underpressure in an economical and convenient manner, and to disconnect anycask of the series from the remainder without disturbing them orchanging the pressuretherein.

The nature of thefinvention consists in certain novel combinations ofparts, as will. be hereinafter more fully set forth.

In the annexed drawings, the letter A des ignates fermenting-casksarranged on a suitable cradle in two series, the one above the other.

The end casks of each series are provided with fermenting-bungs B,consisting, essentially, of the tube A, having a screw-thread at itslower end, a cap, 0, passed over the open upper end of said tube andprovided with a rubber bearing, a, for the end of the said tube, insideperforated guide-flanges, b, and flange or shoulder c, to support theannular weights cl, that are passed over the said cap. The pressure inthe casks raises the cap when it is sufficient to overcome the weights,and the excess having passed out through the perforations of theflanges, the cap again falls and closes the bun g automatically. Thispressure is cut off from the cap. by a cock, at, in tube A, whennecesssary.

The tube A is provided upon opposite sides,

below the cock cl, with nozzles e e 0, the two former being in line witheach other, and the latter at right angles thereto, all the nozzlesbeing preferably in the same horizontal plane.

The casks in each row between the end ones are provided with screw-plugsD,'having nozzles t t" t, in all respects similar in construction andrelative position to those of the fermenting-bungs. These nozzles areeach provided with cut-ofl' cocks l of suitable form. The bungs andscrew-plugs of the lower row of easks'are brought to a level with thoseof the upper row thereof by means of the pipes G.

J indicates tubes of metal, or, if desired, of

any flexible material, connecting the nozzles i i and e c of the plugsand bungs, and coupled thereto in any suitable manner, the rear pair ofbungs being connected by a pipe, J.

The cocks d I being first opened, that one at the end of the series ofpipes farthest from the air-induct pipe J excepted, air is forcedthrough said pipe J into the bungs, plugs, and pipes J, and passes intothe casks of both series in an equal degree, and thepressure increasesuntil it becomes sufficient to raise the caps 0, weighted to resist acertain deter mined pressure, when the excess passes off and the capsfall. Thiswill occur as often as the predetermined pressure is exceededautomatically.

the case may be, pertaining to said cask are out off, and a pipe of anair-pump coupled to nozzle e or 11. Its cock is then opened and pressureapplied by the pump until the cask is emptied by displacement.

What I claim as new, and desire to secure by Letters Patent, is- V Thecombination, with fermenting-oasks A,

arranged in rows, and automatic fermenting- In testimony that I claimthe above I have bungs B, in the end casks of the row, and prohereuntosubscribed my name in the presence vided with the nozzles e e 6, havingcut-off of two Witnesses.
